It would be nice if we could log somehow if an enduser run a workflow and during a REST call an error occurs, then later a developer could check these log files. Or if the issue is not reproducable in DEV environment, only in PROD/TEST env. (like a similar functionality in Flow Classic).

A use-case from partner:
"If the user experience problems occasionally and we can’t recreate it in the debug.
Another example, sometimes when I get long responetimes during testing I cannot see if that is because of M3 or not. Next time I run it it is quick again."
